Zhiyuan Yang commented on TEZ-3337: ----------------------------------- This issue doesn't apply for ATS related things. When we convert TaskAttemptFinishedEvent to either TimelineEntity or JSONObject, we skip the null fields. > Not log empty fields of TaskAttemptFinishedEvent to avoid confusion > ------------------------------------------------------------------- > > Key: TEZ-3337 > URL: https://issues.apache.org/jira/browse/TEZ-3337 > Project: Apache Tez > Issue Type: Bug > Reporter: Zhiyuan Yang > Assignee: Zhiyuan Yang > > For successful task attempt, we don't record the containerId, which cause > "containerId=," in the INFO logs.
